OF NEW YORK, N. Y.

IMPROVEMENT IN SOCKETS AND STANDS FOR LAMPS.

Specification forming part of Letters Patent No. 205,376, dated June 25,1878; application filed June 5, 1878.

To all whom it may concern:

Be it known that I, JosEPH GALLINGER, of the city, county, and State ofNew York, have invented a new and Improved Socket and Stand for Lamps,which invention is fully set forth in the following specification,reference being had to the accompanying drawing, in which- Figure 1represents a vertical central sec tion. Fig. 2 is a horizontal sectionin the plane 00 :r, Fig. 1.

Similar letters indicate corresponding parts.

This invention relates to that class of lamps which are provided with afastening device for a shank on the lamp-fount, and around which isarranged a metallic casing for concealing the fastening device.

My invention consists in a peculiar construction and arrangement ofparts, whereby both the metallic shell and the fastening-thimble areconfined in a depression in the upper end of the stand by means of ascrew-bolt passing through the lower ends of both said shell andfastening-thimble.

In the drawing, the letter A designates my stand, the foot to andstandard I) of which are made in one piece, of glass or other vitreousmaterial, the whole being produced in a suitable mold, so that it can bemade very cheap, and at the same time in any desired plain or ornamentalform. The stand A is made hollow, and in the inner surface of its footare formed recesses c c, for the reception of a metallic cross-bar, d,through which extends a screw-rod, e, that forms the connection betweenthe stand and the socket B. In the top of the standard I) of the standis formed a depression, f, to engage with a projection, 9, formed at thebottom of the socket, so that when the nut of the screw-rod e is screwedup the socket is firmly and securely retained on the top of the stand.

The socket B is composed of an external shell, g, and an internalfastening device, h.

The shell g is bell-shaped, or made in such a form that it fits theconvex surface of the bottom part of the lamp-fountain G, and thefastening device, which I have represented in the drawing, consists of asheet-metal screw, adapted to engage with a screw-thread formed on theshank of the fountain. I do not wish to confine myself, however, to thisprecise form of the fastening device, since various fastening devicescan be used without deviatin g from my invention.

The shank of the lamp-fountain may, for instance, be provided with lugsprojecting from its sides, and adapted to engage with lL-shaped slotsformed in the fastening device it.

By these means I am enabled to connect the lamp-fountain and the socketin a quick and expeditious manner without the use of plaster-of-paris orother cement; and, since the fastening device It is concealed by theshell g, the good appearance of the lamp is preserved.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with the stand A, having the depression f, and with thefount C, of the shell g, having a projection, g, adapted to thedepression, the internal fastening-thimble h, for receiving and holdingthe shank of the fount, and the screw-bolt e. passing through the lowerend 8 of the shell, the fastening thimble for confining the said shelland fastening device in the depression f of the shell, all substantiallyas and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 31st day of May, 1878.

JOSEPH GALLINGER.
